Question 1047438: Mimi is doing a research about driving time. She plans on collecting information from her classmates. This sampling method is called...
systematic
stratified
convenience
cluster
I feel this is an example of convenience since Mimi is using her classmates as sampling rather than using a random method. Could you please offer some insight and clarification to be sure I'm on the right track? Thank you!

RE Thank You.
Yes, her classmates are a little too convenient..regardless of the population
(which is not clear)
* Convenience sample - is characterized by the selection of easy to obtain members from the population. (typically not a worthwhile style for a sampling technique)
- A systematic sample is chosen on the basis of an ordered system.
– A cluster sample involves using a simple random sample of evident groups that the population contains.
- A stratified sample results when a population is split into at least two non-overlapping sub-populations.
